i Specification of Letters Patent.

Patented Jury a, 1916.

Original application led January 21, 1913, Serial No. 743,347. Dividedand this application led July 7, 191.4.. Serial No. 849,439.

To all whom it may Concern Be it known that I, Hennen Crimean-iu, acitizen of the United States, residing at Edgewood Park, in the countyof Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Devices for Supporting Fluid-Control Apparatus,of which the following is a specification.

This invention is a division of my `copending application` Serial No.A33-t7, filed January 21, 1913, and relates to an improved device forremovably supporting check valves and similar control apparatus forcontrolling the flow of fluid through conduits, etc.; and it has for itsprimary ohject the provision of an improved supporting means which isdet'achably mounted so that it can be readily removed together with thefluid control device.

The foregoing, together with such other objects as may hereinafterappear or are incident to my invention, I obtain by means of aconstruction illustrated in preferred form in the accompanying drawingswherein I have shown my improvement applied to a metering device.

Of the drawings, Figure 1 is a longitudinal section through a casing inwhich my invention is embodied; Fig. 2 is a similar section with theparts shown in a different position; and Fig. 3 is a plan view of Fig. 1with the top plate and the positive, or normal flow meter, removed.

Referring to the drawings, 3 is a casing in which the fluid controldevice is mounted. The casing is provided with an inlet opening 4 and anoutlet opening 5, the casing being placed in the main (not shown) sothat the ports are in the line of iow through the main. Adjacent to theinlet opening, the casing 3 is provided with a seat 6a on which a sleeve6 is mounted, said sleeve being detachably held in position by means ofscrews 6b or other suitable means. The upper part of the casing isenlarged to form a chamber C, this chamber being closed by means of aremovable cover plate 3a. The sleeve 6, at its inner end, is providedwith a sloping valve seat 7 against which the disk 7a of the swingingflow control device A `(which in the present showing is a normal flowmeter) is adapted to take. The disk 7a is pivotally leading to thenormal flow meter is held in open positionrso that the iow takes placethrough the normal flow meter. When there is a heavy draft-as that, forexample, which takes place in cases of fire-the valve disk 7iL isunseated and assumes the position ;indicated in Fig. 2, the normal flowmeter then lying in the chamber C of the casing 3. The valve disk 16automatically closes when the disk is unseated, and no flow takes pla-cethrough the normal flow meter. In cases of back pressure, the disk 7aacts as a check valve. Y

For measuring abnormal or heavy flows, I have provided a proportionalflow meter B which is mounted in the apertured portion 9 formed in theupper part of the sleeve 6, said proportional flow meter beingdetachably fastened in any preferred manner to the flanges 10. Theproportional flow meter communicates with a port 30 which is formed inthe casing 6, and which opens in the face of the valve seat 7 inposition to be covered by the valve disk 7a. A tongue or nose 33 isdetachably secured to the valve disk 7 a and normally lies in the port30, said nose being tapered so as to automatically proportion theopening of the port 30 to the main opening which is formed when thevalve disk 7 a unseats.

The indicators for the normal flow and proportional flow meters,respectively numbered 20 and 31, are arranged on the exterior of thecasing 3, said indicators being operated by any preferredform of`actuating means D and E connected to the meters. When it is desired toremove, inspect, repair or replace the fluid control devices, the onlysteps necessary are to remove the cap or cover plate 3a, disconnect theactuating means D and E, and take out the screws 6b; and when thishasbeen done, the sleeve 6 and all of the parts that it carries can beremoved intact. It will also be seen that this arrangement makes itpossible to assemble all the partsvand insert them bodily in the casing.The construction is also such that if desired, either' the normal flowmeter or the proportional flow meter can be removed independently of oneanother'. In case it is desired to detach the normal flow meter, theplates 2l are removed; and in case it is'desired to detach theproportional flow meter, the screws 29 are removed.

It will be clear that the arrangement is applicable to a variety ofdifferent forms of fluid control apparatus, and I do not intend to limitthe invention to the application to metering devices which are shown inthe drawings.

A particular advantage incident to my invention resides in the fact thatthe sleeve offers no obstruction to the passage of fluid, while at thesame time ready detachment is possible.

l. In a device of the character described the combination of a casingprovided with a seat, a sleeve resting in said seat, said sleeve having'an attaching flange and being Copies of this patent may be obtained'forive cents each, by addressing the Commissioner of Patents,

provided with a fluid control device adapted to control the flowtherethrough, and fastoning screws passing through saidflange and intothe ca sing, whereby the sleeve and the fluid control device may bebodily removed from said casing.

2. In a device of the character described the combination of anopen-ended casing havinga seat adjacent to one opening, a sleeveresting.,r onl said seat andprovided with a fluid control device, andmeans fordetachably securing the sleeve in position, said casing beingprovided with a detachable cover for the withdrawal of the sleevetogether with its fluid. control device, there being substantially noobstruction inthe chamber of the casing between the sleeve andthe coverwhereby the sleeve may he lifted substantially directly out of thecasingn In testimony' whereof I have hereunto signed my name in thepresence of the two subscribed witnesses.
